Question

question #3 the graph of a polynomial function is shown below. determine the domain of the function. (-3,3) (-∞,0) (0,∞) (-∞,∞)

Explanation:

Step1: Recall domain definition

The domain of a function is the set of all possible input - values (x - values).

Step2: Analyze polynomial function

Polynomial functions are defined for all real numbers. No matter what real - number value of x we substitute into a polynomial function, we can calculate a corresponding y - value.

Answer:

$(-\infty,\infty)$
